The design and layout of the site looks great. I like simple and clean designs. What's the main value that Shotblox has over say Flickr, Divvyshot, etc?
It's basically your own website. you.shotblox.com or CNAME. You also control the design (backgrounds/logos), and it's unbranded on the front except for a link at the bottom.
This isn't a community, as much as it is a website/photoblog for a single photographer.
